LIRA cable integrity management in offshore wind

Wirescan will perform a LIRA cable integrity management during the supply of a subsea export cable to an offshore wind farm in the UK. The assignment includes to travel to the subsea cable manufacturer and perform a LIRA reference test before and after load-out, and then again to perform a new test when the cable has been shipped to a North Sea dock for re-spooling to the transportation vessel.

After the cable laying, trenching and rock dumping, Wirescan will perform a new LIRA test and compared the result with the previous measurements. The value of the test s is to do risk management during the supply of the cable, and – in case of any damage during one of the supply processes – allocate the responsibility to the correct subcontractor.
